Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Satellite television systems face challenges in providing a consistent customer experience across different electronic devices due to varying signal processing and reception, leading to inconsistent quality and customer experience.
Innovation Solution
A communication system that uses a local area network to communicate an audio-visual stream and remote user interface from a server device to client devices, allowing these devices to render displays and generate key commands, thereby synchronizing the user experience across multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If each electronic device processes signals locally, then device functionality is enhanced, but customer experience consistency deteriorates
Solution Approach 1:
A signal processing system is introduced as an intermediary between the signal source and individual electronic devices. This intermediary centrally processes and standardizes signals before distribution, ensuring consistent customer experience across all devices while preserving each device's local functionality. The intermediary normalizes signal parameters and formats to guarantee uniform performance.
Solution Approach 2:
The system dynamically adjusts signal parameters (such as encoding format, resolution, and transmission characteristics) based on device capabilities and network conditions. By centralizing parameter management and standardizing signal characteristics before distribution, the system maintains experience consistency while allowing devices to operate with their full functional parameters.
2Device complexity
If simplified clients are used, then device complexity is reduced, but customer experience quality may deteriorate
Solution Approach 1:
The signal processing system serves as an intermediary that compensates for the simplicity of client devices. It performs complex signal processing, error correction, and quality optimization centrally, then delivers standardized signals to simple clients. This ensures high experience quality without requiring complex client hardware or software.
Solution Approach 2:
Instead of requiring each client device to have complex processing capabilities, the system creates and distributes standardized signal copies that are optimized for consistent performance. The complex processing is done once at the source, and simplified copies are distributed to all clients, maintaining quality while reducing device complexity.
3Reliability
If extensive custom software is implemented at each device, then customer experience quality improves, but device complexity and cost increase
Solution Approach 1:
The signal processing system acts as a central intermediary that implements all necessary quality assurance, error correction, and optimization functions. This eliminates the need for extensive custom software at individual devices, as the intermediary handles these functions centrally for all clients uniformly.
Solution Approach 2:
The signal processing system provides universal signal processing and quality management functionality that works across all device types. Instead of requiring device-specific custom software, the system uses a single multi-functional processing platform that adapts to different devices while maintaining consistent quality standards.

AI summary
A system and method for controlling a communication system includes a local area network, a first client device and a first server device in communication with the first client device through the local area network. The first server device communicates an audio-visual stream and remote user interface data to the first client device through the local area network. The first client device renders a display using the audio-video stream and the remote user interface. The first client device generates a key command and communicates the key command to the first server device in response to the remote user interface data.
